The inner edges of the inwardly or transversely extendlng web portions of these side stakes extend 'downward and inward at an incline, so' that 3 than 'of the car.

webportions are wider at the bottom' atthe top, and the bottoms of the web portions aresecured, by 'fneans ofconnect- 11lg ahgles l, to the transverse beams. angle-iron m extends along the-upper edgeofeach side frame, and a similar angle- Iron) n'extends' along the lower ed e of each side frame formin the lower me'm er there-- of, These angleelrons thus form, respectively, the to nd bottom chords of trusses, which exten longitudinally from end to end The inner side stakes form the upright compression or strutmembers of such trusses, and the inclined tieieces 0, (finally of Whichextend upward "and longitu the side frames from thebottom of the side stakes to the tops of thenext adjacent side stakes, form tension members of such trusses.

- portions of the side frames members of-the frame corner brace-plates incline from the tops-of the'side stakes'pr struts 1dineath' and secure These inclined tension members are secured to the top' and bottom chords of" the trusses. Tension members p "at the opposite ends: of each side frame extenddownward and at an longitudinally of ,the side frames body-bolsters and or supporting the extending longitudinally beyond the bolsters.

For-bracing the ends of the car-frame and forming horizlontaHy aI-ched'bracing connections between the ends of the longitudinal reetly over the supportin form tension members f are provided and mounted at eachlcorner o the ear. Thesem'orner brace-plates each have projecting (portions 1, extending beto the lower members of the side frames,- and end portions .9, which ex arched edges.

tend transversely toward the center of the caradj'ac'ent to the end sill andsecured to the transversely-extending plates 25, which may form a part of the end sills. The inner edges of the plates are convex orcurved so that they form portions of horizontal arches. A central brace-plate member uis secured to the"transversely-extending plate or end sill membert at each end of the car and has a central portion oextending over the longitudinal central sill mechanism of the car, each of such central brace-plate members being provided with transversely-extending end portions to and curved or horizontally- The inner edges of the corner bracelate members being also similarly curve 'or arched, it will be seen that a double horizontal arch is formed connecting the end zontal side frames or trusses and with-the longitudinal center sills and form double longitudinal 1 arches adapted to efficiently resist the horistresses and strains to which the framework is subjected in operation. End frames as extend from side frame to side frame at the opposite ends of the car and are provided with end stakes g, which may be of the same construction as the side stakes already described.

In' order to provide. suitable dumping mechanism adapted to form a fiat-bottom car. when in closed position and to be moved to inclined dumping position, so as to dump the load, dumping-doors 2, which extend 1011 gitudinally of the car, are pivotally connected at their inner side edgeswith the longitudinal center sills or central floor portion of the car by means of hi'f fges 3, so that their outer swinging edges are adapted to swing upward to closed position beneath and in engagement with the lower member of the .adj acent side frame and downward to inclined dumping position.

- Rotatable reciprocatory shafts 4 extend longitudinally of the car beneath the swinging portions of such dumpin -doors and are supported upon inclined tradlrs 5,- which are secured to the transverse beams by means of bolts of in any ordinary' and well-known manner.. These track portions extend downward and inward at an incline toward the center of the car, and the reciprocatory shafts already described move at a correspondin incline.v The dumping-doors are provide on their under sides with depending tapered or inclined cams or lugs 6, the lower edges 'or surface portions of which extend'downward and outward at an incline and are adapted to be supported upon the reciprocating shaft or upon supporting sleeves or wheels 7 upon such shafts: The outer lower ends of the inclined lugs 6 have bottom por- 'tions 8, which extend substantially hOIIZOIltally or at an angle to the inclined portions of the lugs, so as to form a base adapted to sup ort the door when in closed position. Eac of the reciprocating shafts 'is'providcd with a worm-wheel 9, in toothed engagement with. a worm 10, which is mounted rotatablyin the ends of the arm portions 11 of the bracket 12, which bracket is provided with a perforation 13, through whlch the reciproeating shaft 4 extends. The arms of this bracket are provided with perforations 14, in which bearings 15 are rotatablymounted, and these bearings are provided with squared or angular axial perforations 16, into which a similarly-squared end ortion 17. of an operating staff or shaft 18 s slidably mounted.

The upper end of this operating stafl or shaft is rotatablymounted in a bracket 19, which is pivotally secured to the end frame of the car by means of'a pivot 20, and an operating hand-wheel 21 is mounted upon the upper end of the operating-shaft, by means of which the shaft may be rotated. The
